Slide Rule Manuals

Slide rules prices are strongly influenced by the general availability of a specific slide rule model; manuals are as well - just good ol' supply and demand in action. However, some manuals are much harder to find than the rules they originally came with (engineers never read manuals, they just stick them on the bookshelf, or, toss 'em). The upshot: some of these manuals have what seem like screwy prices to me. But when I adjusted them to what they seemed was right, either I would immediately sell the copy(ies) I had and wait months to find another, or it would sit. And sit. So the prices may seem screwy, but they are dictated by those fiscal demi-gods, the Market Forces.
